\ of a hazardous character and special objects.

of the invention are to provide a dry hose system for the purpose, which will be of simple, practical design. sturdy construction and consisting of but relatively few non-comph cated parts Capable of withstanding rough usage without getting out of order. I

A further special'object is to provide a delivery system of the character outlined above, which will be self-protective so as to automatically shut ofi flow in case of any break in the connections.

These objects and others of a similar desirable nature are attained in this invention by certain novel features of construction. combinations and relations of parts, as will be clear from the following specification.

The drawings accompanying and forming part of the specification illustrate certain practical embodiments of the invention, but

it should be understood that the structure and arrangement may vary within the broad scope and intent of the description and claims.

- Figure 1 is a broken part sectional view of the delivery portion of the apparatus, back to the meter.

Figures 2 and 3 are broken sectional dietail views as taken on substantially the lines 2'-2 and 3-3 of Figure 1.

- Figure 4 is an illustration of the complete system in the simple form in which a pump is employed to transfer liquid direct from a storage tank into the discharge hose.-

Figure 5 is a similar illustration of a pressureform of the system in which the pump is automatically controlled to maintain a'sup} ply of liquid under pressure in an auxiliary tank. from which the discharge stand'or stands derive their supply.

In the simplified or fundamental form of the apparatus shown in Figure 4, an electric pump illustrated at 7 is employed to transfer liquid from the storage tank 8 through lines 9 and 10 to a hose 11 and a continuous flow metered delivery nozzle control is effected by a valve 12 in the delivery line at the head of the hose and a simultaneously operating electric switch 13 controlling the motor.

LIQUID-DELIVERY SYSTEM.

Application filed October 1, 1927. Serial no. 223,255. i

For simultaneously operating the delivery 'valve and switch, a Bowden wire connection 14. is provided between the crank 15 of'a pivoted nozzle handle 16 and the .crank'arm 17 of the valve, the switch as shdwn particularly in Figure 2 being arranged concentrically of the valve shaft 18 and having its arbor suitably keyed in the end of the valve shaft, as

indicated at 19. For supporting the switch in this relation, the same is shown carried by a cap or housing 20 deta'chably secured to the valve head at 21 and to prevent any gasoline or liquid entering the switch box, a cap 22 is shown carried by the valve stem, covering the stuffing box 23 of the valve and serving as a closure to the open inner, side of the guided in a flexible conduit 26 co-extensive with and held to the hose by supports or guides 27. The nozzle is shown equipped.

with a final discharge valve 28 operated by a handle 29, which valve is open when discharge of liquid is to be made under control of the handle 16.

A suitable flow meter 30 in the delivery line. at the inlet end ofthe hose. enables any desired quantities of liquid to be discharged,

governed instantly by the nozzle control. Q

The individual pump system described has certain advantages in the way of simplicity,

fewparts. etc.. and is particularly advantageous for small installations or places where the demand is uncertain.

For larger installations and in places where the demand is more or less continuous, it is more advantageous to use the pressure system shown in Figure 5. This system operates on the same generalprinciple as the one first disclosed, the nozzle control through the Bowden wire connection directly operat- K but whereas in the first case the electric switch served to controkthe operation of an electric pump, in the Second instance the ing a delivery valve and an electricswitch;

pressure branches 34 leading to the diiierent stands.

switch is utilized to control a solenoid valve governing admission of liquid under pressure into the delivery line.

This solenoid valve is shown at 31 interposed in tank 33, said delivery line having The wiring from the switches tothe solenoid valve may be carried back through a suitable conduit System35, it being understood that the switch at each stand is connected with the solenoid valve so that said valve'will open each time the switch at any one of the delivery stands is closed.

v In the particular pressure system 1llustrated, liquid is drawn from a main storage tank 36 and transferred by a pump 37 through tion will pull the valve at the head of the hose open switch on the valve head will be thrown to to deliver liquid and simultaneously the close the circuit of the solenoid valve, which tank to the delivery line.

' the delivery line.

P or pressure control valve,

- ery line, discharge hose,

pressure valve will thereupon opens the full force of the pressure Thus, with the operation of the nozzle grip, the delivery line is opened to the discharge hose and the line is put under the proper delivery pressure. With the release of the grip handle on the nozzle, the delivery valve is automatically closed and substantially simultaneously therewith, the switch is thrown to .open the circuit of the solenoid vzve, which automatically closes to take the pressure off Thus the delivery line is subjected to pressure only when the delivery valve is opened and there is no standing pressure on the delivery valve 'or meter. The main however, traps the flow-back in the delivery so that there will be practically a solid body of liquid, ready for instant delivery the moment any one of the delivery valves is opened. The system 'is entirely self-protective because in the event of any break inthe circuit, the refuse to operate and any break in the hose will bepractically certain to render the Bowden wire connection inoperative.
